- Subject: octave2.1-forge: some patches
- From: Francesco Potorti` <Potorti@isti.cnr.it>
- Date: Mon, 03 Dec 2007 16:36:37 +0100
- Message-id: <E1IzDLZ-0001A4-6S@tucano.isti.cnr.it>
Package: octave2.1-forge
Version: 2006.03.17+dfsg1-3
Severity: minor
File: /usr/share/octave/site/api-v13/m/octave2.1-forge/signal/pwelch.m
This patch allows using the default argment [] for the last three args
range, units, trend and corrects some documentation bugs.
The last hunk of the patch corrects a problem whereas title, axis labels
and grid are deleted just after the plot is shown.
